Fix resource leaks, bounds checks, and missing @Override annotations

[Copilot]

Addresses three code quality issues from parent PR review comments:

Resource Management

• Wrapped InputStreamReader in try-with-resources in AbyssTrialSpawnerManager.java to prevent resource leak

Bounds Validation

• Added length check in MiaUtil.parseResourcePath() before substring operation to prevent StringIndexOutOfBoundsException when filePath.length() == basePath.length()

// Before: Would throw on equal-length paths
var trimmedPath = filePath.substring(basePath.length() + 1);

// After: Returns null safely
if (filePath.length() <= basePath.length()) {
    return null;
}
var trimmedPath = filePath.substring(basePath.length() + 1);

Interface Compliance

• Added @Override annotations to StateAccessor interface implementations in AbyssSpawnerBlockEntity.java (getPatternId(), getPattern(), hasValidPattern())

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
